Value Collection 151280PR Set Screw 5/16-18 X 5/8 in Flat Point

Product Description

The VALUE COLLECTION 151280PR is a flat point set screw designed for secure, non-marring clamping and positioning applications in mechanical assemblies. Manufactured from Grade 8 alloy steel, this screw delivers high tensile and torsional strength suited for demanding industrial and trade environments. The 5/16-18 UNC thread and 5/8-inch overall length make it a standard choice for shaft collars, pulleys, gears, and similar components where a flush or recessed fastener is required. It is driven with a 5/32-inch hex key and conforms to ASME/ANSI B18.3 and ASTM F912 standards. Installation is performed by machinists, millwrights, and mechanical contractors working on rotating equipment and structural assemblies.

This set screw is suited for use in light industrial machinery, HVAC equipment drive assemblies, pump shafts, and other applications requiring a threaded fastener that sits flush with or below the surface of a component. The flat point style distributes clamping force across the mating surface without penetrating or deforming it, making it appropriate for use on hardened or finished shafts. Minimum order quantity is 100 pieces per order, with a package quantity of 1.

Key Features

• Grade 8 alloy steel construction provides high shear and tensile strength
• Flat point tip distributes load without gouging mating surfaces
• 5/16-18 UNC thread for broad compatibility with standard tapped holes
• 5/32-inch hex drive allows precise torque application with a standard hex key
• Conforms to ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• Fractional inch sizing for straightforward specification and replacement

Compatibility

Designed as a standard replacement or stocking fastener for any mechanical assembly using 5/16-18 UNC tapped holes requiring a flat point set screw per ASME/ANSI B18.3 and ASTM F912.

Installation Notes

Set screws of this type are installed by machinists, millwrights, and maintenance technicians using a 5/32-inch hex key. Always de-energize and lock out equipment before servicing any rotating assembly. Apply thread-locking compound if vibration is a concern, and verify that the tapped hole meets ASME/ANSI B18.3 tolerances before installation. Do not exceed the rated torsional capacity of the drive socket.
